[PATCH 4/14] deb-pkg: pass Debian maintainer script parameters to packaging hook scripts

[Frans Pop <elendil@planet.nl>]

The Debian packaging scripts created by the deb-pkg target do not pass
on the standard Debian maintainer script parameters to hook scripts,
which means that those scripts cannot tell whether they are being called
during e.g. install vs. upgrade, or removal vs. purge of the package.

As there are several variantions in how hook scripts are called from
kernel packages, we pass the parameters in the environment variable
DEB_MAINT_PARAMS rather than as extra arguments.

Bump version of builddep script to 1.3.
